Nilight 2PCS Steel Trailer Light Boxes Housing Kit with 6" Oval Red LED Tail Lights and 2" Round Red LED Side Markers
Product description
What this kit is for
If your trailer lights look tired, outdated, or you’re simply trying to tighten up your night visibility, this Nilight steel trailer light housing kit is built for that job. It combines trailer tail light guards (the steel “boxes”) with LED lights already mounted in the housing, including stop/turn/tail functions and side marker style lights.
On paper, the big value is the all-in-one housing approach. Instead of hunting for separate brackets and trying to mount lights cleanly, you get pre-cut steel housings meant to fit and protect the lights, with wire leads you can hardwire to your trailer wiring. It’s the kind of solution that tends to appeal to people who want a straightforward upgrade for a new or existing trailer—especially when they care about weather resistance and a more rugged mount.
Key features that matter in real use
These housings are made from heavy duty steel with a black powder-coated finish, and they come with pre-cut holes for the included lights. That matters because trailer lighting takes abuse: vibration, moisture, road grime, and the occasional bump. The powder-coated finish and solid housing design are intended to help the setup hold up through all weather elements.
Lighting behavior is also a core part of the pitch. The kit uses SMD LED lighting for red output with different brightness levels based on the function: stop/turn mode is described as high brightness, while the tail/side marker lighting is described as low brightness. In practice, that usually means drivers behind you get a clearer signal when braking or indicating, while the running/tail side visibility stays on.
Wiring is laid out with color-coded leads: a white wire with an O-ring terminal for ground, a black wire for the tail/side marker light, and a red wire for the stop/turn light. If you’re doing a DIY wiring job, having that clarity can reduce the “which wire is which?” stress.
Is it perfect? Probably not for everyone—because installation depends on whether your trailer frame setup matches how you plan to mount or attach the boxes, and hardwiring still takes care and basic electrical discipline.
Installation approach (and where it can feel easy or annoying)
The kit is designed so the lights are mounted on the box already. That simplifies the physical part: you’re mostly focusing on connecting the pigtail wires to the corresponding trailer wires, then mounting the steel housing to the trailer.
Nilight describes installation as possible either by welding the boxes on or bolting them on to the rear, side, bottom, or top frame. That flexibility is useful, but it also means the “best” method depends on your trailer and your comfort level:
- If you can weld, the weld-on approach may feel cleaner and more permanent.
- If you prefer bolting, you’ll need to ensure your trailer frame supports it and that you can secure everything properly.
A practical way to picture it: imagine swapping out an older tail light cluster on the rear frame. You position the steel box so the pre-cut openings line up, attach it to the frame, then connect the ground, tail/marker lead, and stop/turn lead. Once wired and mounted, the lights are already housed where they belong—so you’re not improvising a fragile bracket.

Who it suits best (and who should be cautious)
It’s a solid fit if you want a protected, steel-housing-style lighting setup and you’re willing to do hardwiring. This kit also makes sense if your goal is improving visibility at night with clearly separated brightness behavior for braking/turn signaling versus tail/running illumination.
It may not be the best match if you’re trying to avoid electrical work entirely, or if your trailer’s mounting points and wiring layout don’t align with the way these boxes are meant to be attached. Also, because only the mounting locations and basic wiring colors are provided here, it’s worth double-checking compatibility with your trailer’s existing wiring plan before you commit.
Mini FAQ
Is this kit meant for a new trailer or an upgrade?
Both. The description explicitly frames it as working with a new or existing trailer.
Do the lights mount inside the steel boxes, or are they separate pieces?
The lights are described as mounted on the box already, so you’re hardwiring the leads and then mounting the box.
Can I weld the housing to my trailer?
Yes—Nilight states it can be welded on or bolted on to the trailer frame.
What wires should I connect?
The kit provides color-coded leads: white with an O-ring terminal for ground, black for the tail/side marker light, and red for the stop/turn light.
What should I check before buying?
Confirm your trailer frame has a place to mount the housings (rear/side/bottom/top frame options are mentioned) and verify you’re comfortable hardwiring the provided pigtail wires to your trailer circuits.
Final verdict
Should you buy it? Consider it if you want a rugged steel housing solution for trailer tail lighting, with stop/turn and tail/side marker modes handled by included SMD LEDs—and you’re okay doing the wiring and choosing weld-on or bolt-on mounting. It’s the kind of kit that tends to work well for DIYers who like a more protected mounting setup.
Skip it if you need plug-and-play installation or if you’re worried about fitting the housing to your specific trailer frame and wiring layout. With trailer lighting, those “small fit and wiring” details decide whether a kit feels smooth—or frustrating.
